Um modelo para representação flexível de grupos sociais em simulação de multidão

Abstract

The behavior of pedestrian social groups, such as friends, couples and families, is a very important aspect in crowd simulation. Existing group modeling approaches offer little flexibility in customizing the structure of the groups and the relationships between their members, limiting their power of representation. These approaches also often have limitations related to the ability to represent groups of any size and to aspects related to the cohesion of these groups, such as the ability of their members to walk together and follow the same routes. This work proposes a new model that allows the creation of groups with different structures, with zero, one or more leaders and subleaders. The approach can also represent groups of different sizes, including containing subgroups, and represent different levels of relationships between its members. The model also allows the representation of groups with greater cohesion or with members with greater autonomy in the collision avoidance and in the choice of routes, in addition to the ability to regroup if one or more of its members are left behind. The model also includes a new personality factor that represents the level of individuals’ insistence on moving towards their destinations if they are having difficulty to do it. The approach is based on states that the agents can assume based on their profiles and on the social forces model.
